How does our monetary system work?

📘 In Brief

Our monetary system is based on the principle of trust and debt. Most of the money we use daily is not physical cash, but digital book money created by commercial banks. When a bank issues a loan, it simply credits the borrower’s account – the money is thus created out of nothing, as a debt owed to the bank.

However, this newly created money is tied to a repayment obligation. The borrower owes the bank the loan amount plus interest. The central bank (e.g., the ECB) controls this system by setting the key interest rate and regulating the money supply. It is the only institution allowed to actually print new central bank money, which then serves as reserves for commercial banks.

At its core, our system functions as a cycle of trust: we trust that our money will still hold the same value tomorrow, and banks trust that loans will be repaid. This trust is the actual currency – if it breaks, as in a financial crisis, the entire system collapses because money is based only on promises, not on real values like gold.

🔍 Why This Matters

The monetary system is based on the principle of fiat money: money has no intrinsic value but derives its value from state authority and the trust of its users. Central banks control the money supply by providing central bank money to commercial banks and influencing lending through the key interest rate.

Commercial banks create most money as book money through lending: when a bank issues a loan, a deposit is created in the borrower’s account without any previously saved money needing to exist. This money creation is limited by capital and minimum reserve requirements, not by physical backing.

The system is circular: every loan simultaneously creates a liability, and money is destroyed again through repayment. Stability depends crucially on the solvency of debtors and trust in the currency, not on gold reserves or similar tangible collateral.

📈 Key Points

Our monetary system is based on the principle of fiat money, which has no intrinsic value but is backed solely by state authority and the trust of its users. Central banks create money out of nothing as digital book money by granting it to commercial banks as credit, while commercial banks in turn generate additional demand deposit money by issuing loans to businesses and individuals – over 90 percent of the total money in circulation is thus created as debt.

Every creation of money is inextricably linked to the creation of debt: money exists only as a balance on one side and as a liability on the other. The central bank controls the money supply through key interest rates and minimum reserves, and in crises it also purchases government bonds, thereby pumping money directly into the market. The amount of money in circulation thereby grows faster than real economic output, which generates inflation in the long term – a silent redistribution mechanism from savers to debtors.

The system is ultimately a game of trust: it only works as long as all participants believe that money will retain its value tomorrow and that debts can be repaid. At the same time, it is deeply procyclical, because in booms

🧠 What Investors Should Watch For

The monetary system is based on the principle of book money: over 90 percent of the money in circulation exists only as digital entries in accounts, not as physical coins or notes. Commercial banks create this money by issuing loans – they simply credit the loan amount to the borrower’s account without needing prior savings deposits. The central bank (e.g., the ECB) controls the money supply indirectly through key interest rates and the purchase of securities, thereby influencing banks‘ lending activities.

For everyday life, this means: every euro you spend is a debt owed to the banking system, because money is created in parallel with liabilities. When a loan is repaid, the money disappears from circulation again – it is destroyed in accounting terms. The stability of the system therefore depends on trust in the banks, not on a real gold treasure. Practically, this means for you: your account balance is not a reflection of stored wealth, but a claim on a portion of the economy’s total output, which only works as long as everyone believes in it simultaneously.

📝 Conclusion

Our monetary system is based on credit money, which is created out of nothing by commercial banks with every loan issuance – not printed by the central bank. This demand deposit money arises as an accounting entry when a bank grants a loan and credits the amount to the customer’s account, while a claim is simultaneously created as a liability. The central bank merely controls the framework conditions through key interest rates and minimum reserves, but does not influence the daily money supply, which is determined by private lending decisions. Every euro we possess is therefore someone else’s debt – money exists only as a contra-entry to loans that must be repaid. Repayment destroys the money again, causing the money supply to shrink when the economy reduces debt on a net basis. The system only works as long as there is trust in the repayment capacity of debtors and the stability of banks – it is a fragile, cyclical construct of trust and debt.
